Definitions
- the present invention relates to a method of treatment, and more particularly of filling the medullary canal with natural fibers used in toothbrushes.
- the natural fibers used for making toothbrushes such as boar or pig hair from Tchunking, have a general appearance that looks like a mini pipe.
- the object of the present invention is to propose a method for treating the end of natural fibers, making it possible in particular to obstruct the free end of the medullary canal of these fibers in order to prevent any foreign body from entering it.
- the process for treating natural fibers used for making toothbrushes is of the type comprising the steps known per se consisting in applying the free end of the fibers to a grinding wheel in a combined movement composed of a rocking back and forth of the fibers above the grinding wheel on either side of a plane perpendicular to the grinding plane and composed of a simultaneous rotation between the grinding wheel and the fibers, around '' an axis substantially perpendicular to the grinding plane in which the combined movement further comprises the driving in rotation of the grinding wheel around its axis arranged parallel to the grinding plane, and the duration of a back-and-forth rocking of the fibers above the grinding wheel corresponds to the duration of a complete rotation between the fibers and the grinding wheel, in the grinding plane.
- the method consists in applying the fibers a first time on the grinding wheel according to the previously defined combined movement, then in spreading the end of the fibers away from the surface of the grinding wheel, and in reapplying the fibers a second time. fibers on it, in the same combined movement.
- the method consists in applying the end of the fibers to a grinding wheel according to the previously defined combined movement, then in moving and applying the fibers above a second grinding wheel the same combined movement .
- the fibers thus applied to the pack can be joined by bundles according to any assembly or be previously arranged on the support of a toothbrush.
- FIG. 2 shows a device used for implementing a variant of the method according to the present invention consisting in applying the ends of the fibers to the grinding wheel 10 for the first time according to the combined movement described above, then moving and apply the fibers over a second grinding wheel 20 in the same combined movement.
- the method of treating and obstructing the medullary canal of each fiber then consists, firstly, in applying the end of the fibers to the grinding wheel 10 in a pendulum movement between two extreme positions 14 and 14 ′, then in moving in a second step the fibers above the second grinding wheel 20 and to apply thereto, in a third step, the end of these in a pendulum movement between two extreme positions 24 and 24 ', the toothbrush then being removed from the grinding station, as shown by the reference arrow A in FIG. 2.
- the duration of a rocking back and forth of the fibers above each grinding wheel corresponds substantially to the duration of a complete rotation between the fibers and the grinding wheel, in the grinding plane.
- each of the three times previously defined may last approximately half a second.
- the process which is the subject of the present invention is well suited to all fiber diameters, whether these are extra hard, hard, medium or flexible.
- the implementation of the method on the other hand has the advantage of rounding off the end of the fibers and thereby rendering them non-aggressive for the gums.
- the present invention is not limited to the embodiment which has just been described, from which other forms and other embodiments may be provided, without thereby departing from the scope of the invention , it is possible, for example, to obtain a rotation between the fibers and the grinding wheel, in the grinding plane, by rotation of said fibers and no longer of the grinding wheel.
